Among the eccentric and unpredictable members of the Tenmon Club, Rikei Hiromatsu stands out as a rare beacon of common sense. Typically reserved and soft-spoken, she takes it upon herself to call out her clubmates whenever their antics go off the rails. Outside of club activities, she enjoys dabbling in cartomancy, maintaining her composed demeanor—until anything cat-related enters the picture, at which point her rational facade completely unravels, revealing an uncontrollable passion for felines.
